A later type of a recoil booster designed in 1904 by Trevor Dawson and J. Recoil boosters ( avant la lettre) similar to his patent were imported to Russia and after some modifications were adopted in the M1905 3-line machine gun, while another derivative was adopted by Germans in 1915 on their MG 08 guns. In his patent application on an "apparatus for increasing the recoil energy" in October of the same year the inventor stated: "It has been found that with cartridges such as those above referred to the recoil energy is in some instances too feeble to satisfactorily operate the breech mechanism". When Hiram Maxim had his machine gun trialed by the US Navy in their new 6 mm smallbore cartridge in the summer of 1894, he noticed that the lack of recoil from the latter was negatively impacting his design. However, unlike a muzzle brake, a muzzle booster uses the pressure of the expanding gases, rather than the reaction force, and it does not alter the felt recoil of the weapon, it merely adds more energy to the operating components. The muzzle booster is distinct from the muzzle brake, which is designed to use the propellant gases to reduce the recoil of the firearm. In spite of its name, a muzzle booster does not increase muzzle force or velocity but instead is usually used to improve the reliability and/or rate of fire of a recoil operated firearm. MG 42 machine gun, which featured a large muzzle booster at the end of the barrelĪ muzzle booster or recoil booster is a device fixed to the muzzle of a firearm, intended to harness the energy of the escaping propellant to augment the force of recoil on portions of the firearm.
